Answer:
They have same density
Explanation:
The density of an object is defined as
where
m is the mass of the object
V is its volume
Let's call 
and 
the mass and the volume of ball C, respectively. Therefore, the density of ball C is:
We know that the volume of ball C is 3 times the volume of ball D, so
And we also know that ball D has 1/3 the mass of ball C:
So, the density of ball D is:
Therefore, the two balls have same density.

The Linear momentum depends on
1) Mass
2) Linear Velocity
The angular momentum depends on
1) Inertia
2) Rotational velocity
<u>Given that</u>
Speed = 60 Km/hr
In one hour, how much distance travelled by car
We know that
Distance = Speed × time
S = 60 × 1
S = 60 Km
In one hour car will travel 60 Km
